Rob,
The canopy is about 6" high. Not much higher than that. I put four 4" DC fans in there as I know I will be putting a couple of MH's in there down the road. For now it's VHO's only. I have fought heat issues before and don't wnat to mess around this time.
And she's up n running..

That is for sure.
Chris,
yeah they are. Ryland had them on there when I bought the tank and stand. Never took them off.
lol
